IMPROVEMENT |N LooM wEFT-FoRKs.

Specification forming partof Letters Patent No. 156,403, dated November 3, 1574; application filed i v October 14, 1874.

To all whom it may concern:

Be it known .that I, NICHOLAS I. ALLEN, of Hopedale, of the county ot' Worcester and State of Massachusetts, have invented a new and useful Improvement in Stop-Motion Forks for Looms; and do hereby declare the same to be fully described in the following specification and represented in the accompanying Figure 1 denotes a top view, Fig. 2 aside view, Fig.,3 a bottom yiew, and Fig. 4 a transverse section, of a iilling-fork with my improvement. Fig. 5 is a top view, and Fig. 6 a side View, ot' another such fork with my addition and the fork somewhat diit'erently oonstructed.

My invention consists in the combination of a pivotal bridge with the outer and middle tines of the fork, such bridge being extended across and secured to them, in order to give support to them, and particularly to the middle tine, so as toprevent it, or it and its shank,

lwhile in use, from breaking or being broken away or separated from the tlankin g tines and their shanks.

The invention has reference tol stop-motion lling-forks made of wire, essentially as represented in the United States Patent No. 139,251, dated May 27,1873, and granted to Jacob H. Knowles.

In the drawings, the fork is represented as having three tines or prongs, a b c, and with the shank portion e of the middle prong b without any pivotal helix, especially when between the pivotal helices ff of the other prongs, as shown in Figs. 1, 2, and 3. The

' shanks of the prongs are soldered together.

The pivotal bridge is exhibited at A, it, as represented in Figs. 1, 2, 3, 4, being a short metallic tube extended through the helices of the outer prongs, the middle prong or the shank thereof resting directly upon such tube at its middle, the bridge being -soldered to the helices, and the middle prong or its shank.

It will be seen that the tube,'while supported by the helices', stays and supports the middle prong or its shank, and, besides, gives support and connection to helices.

In Figs. 5 and 6 the tubular bridgeAis represented'l as arranged below and against all the prongs, neither of which, as shown, has a pivotal helix, the tube being secured to the several prongs by solder run between it and them, and also between them.

The tubular pivotal bridge applied to and combined with the wire iilling-tork adds very materially to its strength and durability, besides bein g useful in other respects.

I do not claim a stop-motion illing-fork constructed of wire, as represented in either ot' the United States Patents N o. 114,307, dated Mcy 2, 1871, and No. 139,251, dated May 27, 1873.

i What I claim as my invention is as follows, VIZ! In combination with the wire filling-fork, as described, the tubular bridge A, arranged with or applied to 4its tines a, b c, and their compound shank, all substantially as specitied.
